/* XXX A note on the perl source internal type system.  The
   original intent was that I32 be *exactly* 32 bits.

   Currently, we only guarantee that I32 is *at least* 32 bits.
   Specifically, if int is 64 bits, then so is I32.  (This is the case
   for the Cray.)  This has the advantage of meshing nicely with
   standard library calls (where we pass an I32 and the library is
   expecting an int), but the disadvantage that an I32 is not 32 bits.
   Andy Dougherty	August 1996

   There is no guarantee that there is *any* integral type with
   exactly 32 bits.  It is perfectly legal for a system to have
   sizeof(short) == sizeof(int) == sizeof(long) == 8.

   Similarly, there is no guarantee that I16 and U16 have exactly 16
   bits.

   For dealing with issues that may arise from various 32/64-bit
   systems, we will ask Configure to check out

   	SHORTSIZE == sizeof(short)
   	INTSIZE == sizeof(int)
   	LONGSIZE == sizeof(long)
	LONGLONGSIZE == sizeof(long long) (if HAS_LONG_LONG)
   	PTRSIZE == sizeof(void *)
	DOUBLESIZE == sizeof(double)
	LONG_DOUBLESIZE == sizeof(long double) (if HAS_LONG_DOUBLE).

/*
   XXX LEAKTEST doesn't really work in perl5.  There are direct calls to
   safemalloc() in the source, so LEAKTEST won't pick them up.
   (The main "offenders" are extensions.)
   Further, if you try LEAKTEST, you'll also end up calling
   Safefree, which might call safexfree() on some things that weren't
   malloced with safexmalloc.  The correct "fix" to this, if anyone
   is interested, is to ensure that all calls go through the New and
   Renew macros.

=head1 SV Manipulation Functions

=for apidoc Am|SV*|NEWSV|int id|STRLEN len
Creates a new SV.  A non-zero C<len> parameter indicates the number of
bytes of preallocated string space the SV should have.  An extra byte for a
tailing NUL is also reserved.  (SvPOK is not set for the SV even if string
space is allocated.)  The reference count for the new SV is set to 1.
C<id> is an integer id between 0 and 1299 (used to identify leaks).

=head1 Memory Management

=for apidoc Am|void|New|int id|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function.

=for apidoc Am|void|Newc|int id|void* ptr|int nitems|type|cast
The XSUB-writer's interface to the C C<malloc> function, with
cast.

=for apidoc Am|void|Newz|int id|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<malloc> function.  The allocated
memory is zeroed with C<memzero>.

=for apidoc Am|void|Renew|void* ptr|int nitems|type
The XSUB-writer's interface to the C C<realloc> function.

=for apidoc Am|void|Renewc|void* ptr|int nitems|type|cast
The XSUB-writer's interface to the C C<realloc> function, with
cast.

=for apidoc Am|void|Safefree|void* ptr
The XSUB-writer's interface to the C C<free> function.

=for apidoc Am|void|Move|void* src|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memmove> function.  The C<src> is the
source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
the type.  Can do overlapping moves.  See also C<Copy>.

=for apidoc Am|void|Copy|void* src|void* dest|int nitems|type
The XSUB-writer's interface to the C C<memcpy> function.  The C<src> is the
source, C<dest> is the destination, C<nitems> is the number of items, and C<type> is
the type.  May fail on overlapping copies.  See also C<Move>.

=for apidoc Am|void|Zero|void* dest|int nitems|type

The XSUB-writer's interface to the C C<memzero> function.  The C<dest> is the
destination, C<nitems> is the number of items, and C<type> is the type.

=for apidoc Am|void|StructCopy|type src|type dest|type
This is an architecture-independent macro to copy one structure to another.

=for apidoc Am|void|Poison|void* dest|int nitems|type

Fill up memory with a pattern (byte 0xAB over and over again) that
hopefully catches attempts to access uninitialized memory.
